patterns and changes in the sea ice environment to provide information to Labrador Inuit that can inform travel on the sea ice. Paul McCarney, Research Manager with the Nunatsiavut Government, coordinated the work, with additional expertise provided by Eric Oliver, an Assistant Professor of Physical Oceanography at Dalhousie University.  This work is in collaboration with Adrienne Tivy at the Canadian Ice Service and Clark Richards at Bedford Institute of Oceanography. The work relied heavily on the local knowledge expertise and efforts of Joey Angnatok, Mentor-Harvester and Field Researcher with

ocean, but until now it has been unclear where it actually ended up.“Our study has shown how detailed studies of seafloor currents can help us to connect microplastic transport pathways in the deep-sea and find the ‘missing’ microplastics," said Dr. Mike Clare of the National Oceanography Center, who was a co-lead on the research. "The results highlight the need for policy interventions to limit the future flow of plastics into natural environments and minimize impacts on ocean ecosystems”.The lead author of the study, Dr. Ian Kane of the University of Manchester, said

;A.J.'s maritime expertise, leadership acumen, and reputation for building interagency and international relationships will ensure OPC continues to deliver the very best products and services for mariners.”Reiss is a retired Navy Captain who served most of his career as a Meteorology and Oceanography officer including command of a maritime forecast center after early shipboard assignments. He most recently held the position of Division Director of the Ocean Sensing & Systems Application Division at the Office of Naval Research. In this role he was responsible for leading the development

The longest mission to date has been 50 days in the mid-Pacific and one AutoNaut has operated in Force 10 on the Beaufort Scale, during the first Marine Autonomous Systems in Support of Marine Observations (MASSMO) mission, co-ordinated by the National Oceanography Centre and run off the Isle of Scilly and they regularly work in Force 6 and 7.  Projects the systems have worked on include science, civil, energy and defence for applications from fish tracking missions, anti-submarine warfare trials, metocean sensing and water quality monitoring to current

doesn’t provide information regarding the vertical ocean structure, which is all-important. A series of instruments along a mooring is expensive, especially if many types of measurements are to be collected,” explains Dr. Andrew J. Lucas. He is Assistant Professor at Scripps Institution of Oceanography and Department of Mechanical and Aerospace Engineering at UC San Diego, and co-founder of Del Mar Oceanographic.Further offshore, costs continue to mount. Here, instruments are lowered down and pulled up through the water column by diesel-powered winches on a ship.Together with Dr. Robert Pinkel

Meterologists, Oceanographers Help Pave a Safe Path for USN Hospital Ships

USNS Mercy (T-AH-19) arrived safely in Los Angeles last week and USNS Comfort (T-AH-20) arrived safely in New York on Monday. While the Navy’s hospital ships prepare to receive patients, Naval Oceanography’s team of meteorologists and oceanographers ensured these ships were safe from hazardous weather as they traveled to their destinations.On March 20, Fleet Numerical Meteorology and Oceanography Center (FNMOC) rapidly configured two ship-following coupled ocean/atmosphere mesoscale prediction systems (COAMPS) for the USNS Mercy and Comfort. The center of these high-resolution weather

.The current expedition, led by Dr. Nerida Wilson from the Western Australian Museum, began in Fremantle on March 8 and is currently scheduled to continue through April 8. On board are scientists from the Western Australian Museum, Geoscience Australia, Curtin University, and Scripps Institution of Oceanography The science team is using underwater robot SuBastian to collect 4K video and implement cutting-edge sampling techniques from the deep sea. This will allow the research team to get a more complete picture of the biodiversity of this unique environment. The team has uploaded footage of deep sea

It is likely that by the end of this decade eDNA data will be as ubiquitous as the conductivity, temperature, and depth information that dominates physical oceanography today.

Dr Birch spoke about the work and its results at the National Oceanography Centre’s Marine Autonomy and Technology Showcase (MATS) event in Southampton, late last year
